본 발명에서 상기 저융점 열가소성수지 섬유(a)는 해당 분야에서 통상적으로 사용되는 것이라면 제한되지 않지만, 보다 바람직하게는 폴리에틸렌, 폴리프로필렌, 폴리염화비닐, 폴리에스테르, 폴리에틸렌-폴리에스테르 공중합체에서 선택되는 어느 하나 이상을 사용하는 것이 좋다. 보다 바람직하게는 용융점이 80 ~ 120℃인 섬유를 사용하는 것이 좋다.In the present invention, the low melting point thermoplastic resin (a) is not limited as long as it is commonly used in the art, but more preferably selected from polyethylene, polypropylene, polyvinyl chloride, polyester, polyethylene-polyester copolymer It is better to use one or more. More preferably, fibers having a melting point of 80 to 120 ° C are used.
본 발명에서는 상기 저융점 열가소성수지 섬유의 함량은 30 ~ 95 중량%를 사용하는 것이 바람직하며, 30중량% 미만으로 사용하는 경우 목적으로 하는 경량 및 단열, 흡음성을 만족할 수 없으며, 95 중량%를 초과하는 경우 만족할만한 경량화를 달성할 수 없다.In the present invention, the content of the low-melting thermoplastic resin fibers is preferably used in 30 to 95% by weight, when used in less than 30% by weight can not satisfy the desired light weight, heat insulation, sound absorption, more than 95% by weight In this case, satisfactory weight reduction cannot be achieved.
본 발명에서 상기 열가소성수지 중공섬유(b)는 섬유의 내부가 빈 공간으로 형성된 것을 의미하는 것으로, 중공섬유의 내열성이 200℃이상, 구체적으로는 200 ~ 280℃인 것을 사용하는 것이 좋다. 상기 내열성은 유리전이온도 또는 용융온도(용융점)를 의미하는 것으로, 이러한 중공섬유를 사용하는 경우 중공섬유의 내부에 형성된 공동(空洞)이 스탬퍼블 시트 제조장치를 통과하는 과정에서도 상기 저융점 열가소성수지 섬유보다 높은 내열성을 가짐으로써 그 형태를 일정부분 더 잘 유지하여 최종시트의 흡음성 또는 단열성을 증가시켜 준다. 이러한 중공섬유로는 예를 들면, 폴리에스테르계, 폴리에틸렌계, 나일론계, 열융해성 불소수지 등의 열가소성수지 중공섬유를 사용할 수 있으며, 공동(空洞)이 원형, 삼각형 등 어떠한 형상을 갖는 것도 가능하며, 이들에 제한되는 것은 아니다. 상기 열융해성 불소수지로는 테트라 플루오르 에틸렌-헥사 플루오르 프로필렌 공중합체(FEP)，테트라 플루오르 에틸렌-펠플루오르 알킬 비닐 에테르 공중합체(PFA)，테트라 플루오르 에틸렌 -헥사 플루오르 프로필렌-펠플루오르 알킬 비닐 에테르 공중합체(EPA)，테트라 플루오르 에틸렌-에틸렌 공중합체(ETFE) 등을 사용할 수 있다. 이러한 중공섬유를 사용하는 경우, 섬유 내부의 빈 공간에 의해 흡음 및 단열 효과가 더욱 우수하게 된다.The thermoplastic resin hollow fiber (b) in the present invention means that the inside of the fiber is formed into an empty space, the heat resistance of the hollow fiber is preferably 200 ℃ or more, specifically 200 ~ 280 ℃ to use. The heat resistance means a glass transition temperature or a melting temperature (melting point), and when the hollow fiber is used, the low melting point thermoplastic resin is formed even when a cavity formed in the hollow fiber passes through the stampable sheet manufacturing apparatus. By having higher heat resistance than the fiber, it maintains the shape partly better, thereby increasing the sound absorption or thermal insulation of the final sheet. As the hollow fiber, for example, a thermoplastic resin hollow fiber such as polyester, polyethylene, nylon, heat-melting fluorine resin, etc. may be used, and the cavity may have any shape such as a circle or a triangle. It is not limited to these. As the heat-soluble fluororesin, tetrafluoro ethylene-hexafluoropropylene copolymer (FEP), tetrafluoro ethylene-felfluoro alkyl vinyl ether copolymer (PFA), tetrafluoroethylene-hexafluoro propylene-felfluoro alkyl vinyl ether air Copolymer (EPA), tetrafluoro ethylene-ethylene copolymer (ETFE) and the like can be used. In the case of using such hollow fibers, the sound absorbing and insulating effect is further improved by the empty space inside the fiber.

The polyester hollow fiber, which is a raw material fiber, may be either fully stretched or semi-stretched, but it is preferable to use a semi-stretched material in order to highlight the bulky structure by expressing a large difference in shrinkage with the high shrink polyester fiber. In the present invention, it can be produced by the manufacturing method described in Korean Patent Publication No. 10-2004-0049035 as an example of such a polyester composite air interlocking yarn.

또한, 본 발명은 상기 적층시트의 제조 시 사용되는 섬유들의 굵기를 선택적으로 사용함으로써 제조되는 적층시트의 물성을 조절할 수 있다. 특히, 상기 시트 시 섬유는 10 ~ 20 데니아인 섬유를 20 ~ 95 중량%, 2 ~ 7 데니아인 섬유를 5 ~ 80 중량%로 혼합하여 사용하는 것이 바람직하다. 보다 바람직하게는 고융점 열가소성수지 중공섬유 또는 폴리에스테르 복합공기교락사(b)를 10 ~ 20 데니아로 사용하고, 저융점 열가소성수지 섬유(a)를 2 ~ 7 데니아로 혼합하여 사용하는 것이 좋다.In addition, the present invention can control the physical properties of the laminated sheet produced by selectively using the thickness of the fibers used in the manufacture of the laminated sheet. Particularly, the sheet fiber is preferably used by mixing 20 to 95% by weight of the fibers of 10 to 20 denier and 5 to 80% by weight of the 2 to 7 denier fibers. More preferably, the high melting point thermoplastic resin hollow fiber or the polyester composite air entangled yarn (b) is used as 10 to 20 denier, and the low melting point thermoplastic resin fiber (a) is mixed to 2 to 7 denier.

1종류의 매트로 With one kind of mat 적층된Stacked 3-layer 적층시트의 제조 Preparation of 3-layer laminated sheet
5 데니아의 폴리에스테르 섬유(용융온도 110℃) 45 중량%와, 15 데니아의 폴리에스테르 복합공기교락사(용융온도 245℃) 55 중량%를 혼합, 개섬한 후 원통형 실린더형의 카딩기를 통과시켜 매트를 제조하였다. 45 wt% of 5 Denia polyester fiber (melting temperature 110 ℃) and 55 wt% of 15 Denia polyester composite air entangled yarn (melting temperature 245 ℃) were mixed and opened, and passed through a cylindrical cylindrical carding machine. The mat was prepared.
상기 제조된 매트를 세 겹으로 적층한 후, 니들펀칭에 의해 고정하여 20mm 두께로 적층하였다. 이를 스탬퍼블 시트 제조장치로 공급하여 170℃, 200℃, 230℃의 온도로 각각 예열된 롤러를 8M/min의 속도로 통과시켜 10mm 두께의 시트를 제조하였으며, 다시 90℃의 에어 쿨 존을 8M/min의 속도로 통과시켜 7mm두께의 시트를 제조하였으며, 50℃의 워터 쿨 존을 8M/min의 속도로 통과시키고, 30℃의 워터 쿨 존을 8M/min의 속도로 통과시켜 최종적으로 5mm 두께의 적층시트를 제조하였다.The prepared mat was laminated in three layers, and then fixed by needle punching to laminate a 20 mm thick layer. The sheet was supplied to a stampable sheet manufacturing apparatus and passed through rollers preheated at a temperature of 170 ° C., 200 ° C. and 230 ° C. at a rate of 8 M / min to prepare a sheet having a thickness of 10 mm. 7mm thick sheet was produced by passing through the rate of / min, and passed through the water cool zone of 50 ℃ at a rate of 8M / min, and passed through the water cool zone of 30 ℃ at a rate of 8M / min, finally 5mm thickness The laminated sheet of was prepared.
제조된 적층시트를 난연액에 충분히 함침시킨 후 꺼내어 130℃에서 30분간 건조하였다. 제조된 흡음시트 물성을 측정하여 하기 표 1에 나타내었다.The laminated sheet thus prepared was sufficiently impregnated with a flame retardant solution, taken out, and dried at 130 ° C. for 30 minutes. The measured sound absorbing sheet physical properties are shown in Table 1 below.
[표 1]TABLE 1
상기 흡음성은 관내법을 이용하여 측정한 것으로, 250Hz, 500Hz, 1000Hz, 2000Hz에서 측정한 평균값을 나타낸 것이다.The sound absorbency was measured using an in-tube method, and represents the average value measured at 250 Hz, 500 Hz, 1000 Hz, and 2000 Hz.
표에서 보이는 바와 같이, 본 발명에 따른 적층흠음시트는 경량의 시트를 제조할 수 있었으며, 기계적 물성뿐만 아니라 난연성이 우수하여 건축용 내장판재로 사용하기에 적합한 것을 알 수 있었다.As shown in the table, the laminated fault sheet according to the present invention was able to produce a lightweight sheet, it was found that not only mechanical properties but also excellent flame retardancy suitable for use as a building interior plate material.
이상에서 살핀 바와 같이, 본 발명은 저융점의 열가소성수지 섬유와 고융점의 열가소성수지 중공섬유 또는 폴리에스테르 복합공기교락사를 일정 비율로 혼합 하여 사용함으로써 경량화 및 기계적 물성뿐만 아니라 친환경의 난연액을 함침함으로써 우수한 난연성을 갖는 건축용 판재로 적용이 가능하다.As described above, the present invention by mixing a low-melting thermoplastic resin fibers and a high-melting thermoplastic hollow fiber or polyester composite air entanglement in a certain ratio to impregnate the eco-friendly flame retardant as well as light weight and mechanical properties. It is possible to apply to the building plate having excellent flame retardancy.
